“Jennifer did not know, however, if anyone had been hurt by the shooting,” Guthas said Tuesday in an email statement. “Also inside the residence at the time was Diana Freeman, 66, Jennifer’s mother.” According to ajc.com, inside the home, investigators found Freeman, who had been living with the couple, dead from gunshot wounds.

Muriu died from gunshot wounds, Guthas said.

“Investigation is ongoing,” Guthas added. “However, the indications at this point are that Ian Muriu shot and killed Diana Freeman, his mother-in-law, before taking his own life.” Investigators did not release possible motives of the deaths.

The Murius were co-owners of The Spitfire Restaurant at the Barrow County Airport in Winder, according to the restaurant’s Facebook page.

The restaurant opened in May 2011 and is featured in this month’s edition of Georgia Magazine.
